Gata2, a zinc finger TF, is essential for the generation and survival of HSCs in the embryo and has been implicated in the pathogenesis of AML, yet the requirement for Gata2 in adult HSCs and LSCs remains unclear. Using a conditional mouse model where Gata2 was deleted specifically in hematopoietic cells, we show that knockout of Gata2 leads to a rapid and complete cell-autonomous loss of adult HSCs. In Meis1a/Hoxa9 driven AML, deletion of Gata2 impedes maintenance and self-renewal of LSCs. We then performed RNA-seq from sorted control and Gata2 KO LSCs (CD45.2+ c-Kit+) after pIpC treatment in transplanted mice. Overall design: Wild Type and Gata2-/- Meis1a/Hoxa9 LSCs were harvested from mice 24 days after pIpC administration

View SamplesCircadian rhythms are oscillations with a periodicity of 24 hours that are controlled by an endogenous clock and are observed in virtually all aspects of mammalian function from expression of genes to complex physiological processes. The master clock is present in the suprachiasmatic nucleus (SCN) in the anterior part of the hypothalamus and controls peripheral clocks present in other parts of the body . Although much is known about the mechanism of the central clock in the SCN, the regulation of clocks present in peripheral tissues is still unclear. This study is designed to examine fluctuations in gene expression in lungs within the 24 hour circadian cycle in normal animals. The objectives of this study is to identify and analyze circadian oscillation in gene expression in lungs, and to identify the role of circadian regulation in coordinating the functioning of this dynamic organ.

View SamplesHow the various cell-types of the body achieve their specific shapes is fundamentally unknown. Here, we explore this issue by identifying genes involved in the elaboration of the complex, yet conserved, cellular morphology of Müller glial (MG) cells in the retina. Using genomic based strategies in zebrafish, we found more than 40 candidate genes involved in specific aspects of MG morphogenesis. The successive steps of cell morphogenesis correlate with the timing of the expression of cohorts of inter-related genes that have roles in generating the particular anatomical features of these cells, suggesting that a sequence of genetic regulomes govern stepwise cellular morphogenesis in this system. Overall design: 12 samples with three replicates each are provided. GFAP:GFP positive and negative cells were FAC sorted from wild type animals from each developmental stage
